Abbreviation: MUAC, mid-upper arm circumference.
* P < 0.001 (χ2 between incident cases and nonseroconverters significant only between 0 and 12 months; the log-rank test of incidence between age categories was also significant (P < 0.001)).
Percent malnourished defined by MUAC <22.5 cm. MUAC was restricted to participants >15 years of age. There was no significant difference between incident cases and nonseroconverters.
Comparison of groups excluded participants ≤15 years of age and therefore ineligible to be married. No significant difference was shown.
Comparison of groups excluded participants <7 years of age and therefore ineligible for school. No significant difference was shown.
Comparison excluded participants <15 years of age because of nonsignificant employment prior to this age. No significant difference was shown.
